The first legislation that Ferdinand Marcos Jr. signed into law as president is the Subscriber Identity Module or SIM Registration Act or Republic Act (RA) 11934. He signed the law on October 10, 2022 after both houses of Congress transmitted the bill to Malacañang on October 4.

Former president Rodrigo Duterte vetoed the SIM Registration Law earlier this year, due to the belatedly inserted provision on social media registration. Many groups, local and international, panned the requirement for users to use their real names and contact numbers when creating social media accounts.

After the large-scale text phishing scams and spams happening while the law was being revived under the new administration and the removal of the assailed provisions on social media registration and centralized database or SIM register, the legislation seemed to have gotten lesser flak from the public and moved quicker to being passed into law.

However, many of the risks and criticisms raised by various groups on mandatory SIM registration remain:

  • Eradicating the potential for anonymity of communications, as prohibitions of anonymity interfere with the right to privacy and freedom of expression. In repressive environments, anonymity is the only protection enjoyed by whistleblowers, human rights defenders, journalists, political opposition and government critics.
  • Posing risks to the rights to privacy, free expression and information, and association by facilitating targeting, profiling and surveillance
    • Enables location-tracking
    • Enables tracking of device within a mobile network through the collection and identification of the SIM serial number (IMEI) and also tracking of user activities on the device
    • Simplifies communications surveillance and interception
    • Individual’s mobile number could potentially be matched with their political activity or voting preferences (allowing government to identify and target political opponents) or confidential health data, such as people living with AIDS/HIV
    • SIM users’ information can be shared and matched with other private and public databases, enabling the government to create comprehensive profiles of citizens
    • While the law may improve crime investigations and national security, it is equally likely to enable the surveillance of human rights defenders, activists, and other groups whose work deals with anonymity and confidentiality such as doctors, lawyers and journalists
    • May discourage victims of crime or human rights violations or the marginalized by allowing them to speak out against oppression and abuse without fear of retaliation
    • May discourage anonymous tips from whistleblowers
  • Discriminating against marginalized groups or vulnerable sectors
    • Poorest individuals may not have valid identification documents and may be excluded from services requiring such
    • Remote areas have limited telecommunication or internet access
    • Lived names of transgender and gender diverse individuals may be deemed as “fictitious identities” or false information under the law and in the absence of legal gender recognition in the country, and they will be forced to use dead names to register
  • Law grants sweeping powers to the Philippine authorities (unless any of these could be fleshed out or made clearer in the implementing guidelines of the law):
    • Authorities can demand and receive disclosure of information obtained in SIM registration by court order or subpoena, but without adequate independent oversight to monitor government demands for private information disclosure
    • No provisions on secure holding or furnishing of such information
    • No stipulated penalties for private information misuse or resulting dangers or violations to rights of end users (while also removing accountability of telcos for disclosure by request of authorities).
    • SIM spoofing is illegal and punishable with hefty fines and imprisonment under the law except in “authorized activities of law enforcement” and a “court order specifically authorizing the use of caller ID manipulation.”

“We will soon be able to provide law enforcement agencies the tools needed to resolve crimes perpetrated with the use of these SIM cards as well as providing a strong deterrence against the commission of wrongdoing,” Marcos Jr. said in the ceremonial signing of the law.

However, the law only provides penalties for failure to register SIM, penalization for the breach of confidentiality and negligence of telcos; and the spoofing of SIM and use of stolen or previously registered SIM by end users. It does not provide ways to curb SIM-related crimes save for registration and does not provide penalties for those using SIM cards for crime or malicious or unlawful acts against unsuspecting victims except for spoofing.  

Questions on the effectiveness of the crime-curbing powers of mandatory SIM Registration over security risks, state surveillance and social exclusion that became collateral issues in many other countries implementing a similar law have yet to yield satisfying answers.

The Philippines is now one of over 150 countries in the world to have mandatory SIM registration, held in the world over to be for combatting crimes and scams using SIMs. But a2016 GSMA report states there is no empirical evidence that mandatory SIM registration directly leads to a reduction in crime.

Anonymous calls or messages are not only possible through the use of SIM cards and SIM registration eliminates only one of many possible ways to deliver scams (others may go back to email spam or use mobile apps). Criminal elements may find a way to undermine the law and use those who abide by it to bypass the law. Hackers could hack into unregistered SIMs. A single or a handful of unregistered, smuggled or stolen SIM cards could render the law ineffective. When these things happen, all that will be left is a database of personal and other SIM card information controlled by private telcos and the government, for administration, governance, profit or whatever use they see fit or can pass within the legal processes to obtain a citizen’s private information.
